Are mineral oil defoamer water-based or oil-based?
Mineral oil defoamer cannot be used in many industries because it is incompatible with many water-based systems and has poor water solubility. However, some friends asked me why there is a water-based mineral oil defoamer on the market and whether it is It has good compatibility with defoamer of other ingredients, but if you are wondering whether it is water-based or oil-based, let me explain to you the knowledge about mineral oil defoamer today!
Mineral oil defoamer is divided into water-based and oil-based
The main component is mineral oil, which has poor water solubility. It is mostly used in oily systems. It is characterized by high temperature resistance and will not affect its function when used in a strong alkali environment. It has good defoaming and antifoaming functions and has the ability to eliminate water-based and oily mineral oils. The distinction between foaming agents is because the mineral oil defoaming agent used in water-based systems is specially processed, improved and developed, and can be well miscible and dispersed in water-based systems.
Water-based mineral oil defoamer:
It is mainly composed of amides, fatty acids, polyether-modified water-based mineral oil and other substances. It does not contain silicon. It is specially developed to be well dissolved and dispersed in aqueous systems without leaving spots. It has good defoaming and foam suppression and is not easy to bleach and break. It emulsifies and does not fold out. Water-based mineral oil defoamer is mostly used in water-based systems with weak emulsification properties such as water-based coatings, adhesives, and inks. However, its water solubility is still a little worse than that of defoamer with other ingredients. Therefore its price will be relatively low.
Oily mineral oil defoamer:
It mainly contains mineral oil and inorganic hydrophobic particles, does not contain silicone, is resistant to high temperatures and strong acids and alkali, has good defoaming and suppression, and will not cause demulsification, oil drifting or stratification when used, and can be quickly dispersed in the solution to form Stable emulsion without affecting product quality, oily mineral oil defoamer is mostly used in oily systems such as ink printing, resin, ACE coating, adhesive, and oil collection.
